MSS Ch 8: Endocrine Disorders Practice Questions Flashcards
An 18-year-old female client, 5′4′′ tall, weighing 113 kg, comes to the clinic for a nonhealing wound on her lower leg, which she has had for two (2) weeks. Which disease process should the nurse suspect the client has developed?
- Type 1 diabetes.
- Type 2 diabetes.
- Gestational diabetes.
- Acanthosis nigricans.
- Type 1 diabetes usually occurs in young clients who are underweight. In this disease, there is no production of insulin from the beta cells in the pancreas. People with type 1 diabetes are insulin dependent with a rapid onset of symptoms, including polyuria, polydipsia, and polyphagia.
- Type 2 diabetes is a disorder usually occurring around the age of 40, but it is now being detected in children and young adults as a result of obesity and sedentary lifestyles. Nonhealing wounds are a hallmark sign of type 2 diabetes. This client weighs 248.6 pounds and is short.
- Gestational diabetes occurs during pregnancy.
- Acanthosis nigricans (AN), dark pigmenta- tion and skin creases in the neck, is a sign of hyperinsulinemia. The pancreas is secreting excess amounts of insulin as a result of excessive caloric intake. It is identified in young children and is a precursor to the development of type 2 diabetes.
The client diagnosed with type 1 diabetes has a glycosylated hemoglobin (A1c) of 8.1%. Which interpretation should the nurse make based on this result?
- This result is below normal levels.
- This result is within acceptable levels.
- This result is above recommended levels.
- This result is dangerously high.
- The acceptable level for an A1c for a client with diabetes is between 6% and 7%, which corresponds to a 120- to 140-mg/dL aver- age blood glucose level.
- This result is not within acceptable levels for the client with diabetes, which is 6% to 7%.
- This result parallels a serum blood glucose level of approximately 180 to 200 mg/dL. An A1c is a blood test reflect- ing average blood glucose levels over a period of three (3) months; clients with elevated blood glucose levels are at risk for developing long-term complications.
- An A1c of 13% is dangerously high; it re- flects a 300-mg/dL average blood glucose level over the past 3 months.
The nurse administered 28 units of Humulin N, an intermediate-acting insulin, to a client diagnosed with type 1 diabetes at 1600. Which intervention should the nurse implement?
- Ensure the client eats the bedtime snack.
- Determine how much food the client ate at lunch.
- Perform a glucometer reading at 0700.
- Offer the client protein after administering insulin.
- Humulin N peaks in 6 to 8 hours, mak- ing the client at risk for hypoglycemia around midnight, which is why the client should receive a bedtime snack. This snack will prevent nighttime hypoglycemia.
- The food intake at lunch will not affect the client’s blood glucose level at midnight.
- The client’s glucometer reading should be done around 2100 to assess the effectiveness of insulin at 1600.
- Onset of Humulin N, an intermediate- acting insulin, is 2 to 4 hours but it does not peak until 6 to 8 hours.
The client diagnosed with type 1 diabetes is receiving Humalog, a rapid-acting insulin, by sliding scale. The order reads blood glucose level: <150, zero (0) units; 151 to 200, three (3) units; 201 to 250, six (6) units; >251, contact health-care provider. The unlicensed assistive personnel (UAP) reports to the nurse the client’s glucometer reading is 189. How much insulin should the nurse administer to the client? ________
Three (3) units.
The client’s result is 189, which is between 151 and 200, so the nurse should administer 3 units of Humalog insulin subcutaneously.
The nurse is discussing the importance of exercising with a client diagnosed with type 2 diabetes whose diabetes is well controlled with diet and exercise. Which information should the nurse include in the teaching about diabetes?
- Eat a simple carbohydrate snack before exercising.
- Carry peanut butter crackers when exercising.
- Encourage the client to walk 20 minutes three (3) times a week.
- Perform warmup and cool-down exercises.
- The client diagnosed with type 2 diabetes who is not taking insulin or oral agents does not need extra food before exercise.
- The client with diabetes who is at risk for hypoglycemia when exercising should carry a simple carbohydrate, but this client is not at risk for hypoglycemia.
- Clients with diabetes controlled by diet and exercise must exercise daily at the same time and in the same amount to control the glucose level.
- All clients who exercise should perform warmup and cool-down exercises to help prevent muscle strain and injury.
The nurse is assessing the feet of a client with long-term type 2 diabetes. Which assessment data warrant immediate intervention by the nurse?
- The client has crumbling toenails.
- The client has athlete’s foot.
- The client has a necrotic big toe.
- The client has thickened toenails.
- Crumbling toenails indicate tinea unguium, which is a fungus infection of the toenail.
- Athlete’s foot is a non–life-threatening fungal infection.
- A necrotic big toe indicates “dead” tis- sue. The client does not feel pain, does not realize the injury, and does not seek treatment. Increased blood glucose levels decrease the oxygen supply needed to heal the wound and increase the risk for developing an infection.
- Big, thick toenails are fungal infections and do not require immediate intervention by the nurse.
The home health nurse is completing the admission assessment for a 76-year-old client diagnosed with type 2 diabetes controlled with 70/30 insulin. Which intervention should be included in the plan of care?
- Assess the client’s ability to read small print.
- Monitor the client’s serum PT level.
- Teach the client how to perform a hemoglobin A1c test daily.
- Instruct the client to check the feet weekly.
- Age-related visual changes and diabetic retinopathy could cause the client to have difficulty in reading and drawing up insulin dosage accurately.
- The PT level is monitored for clients receiving Coumadin, an anticoagulant, which is not ordered for client with diabetes, type 1 or 2.
- Glycosylated hemoglobin is a serum blood test usually performed in a laboratory, not in the client’s home. The hemoglobin Alc is performed every three (3) months. Self-monitoring blood glucose (SMBG) should be taught to the client.
- The client’s feet should be checked daily, not weekly. In a week the client could have developed gangrene from an injury the client did not realize he or she had.
The client with type 2 diabetes controlled with biguanide oral diabetic medication is scheduled for a computed tomography (CT) scan with contrast of the abdomen to evaluate pancreatic function. Which intervention should the nurse implement?
- Provide a high-fat diet 24 hours prior to test.
- Hold the biguanide medication for 48 hours prior to test.
- Obtain an informed consent form for the test.
- Administer pancreatic enzymes prior to the test.
- High-fat diets are not recommended for clients diagnosed with diabetes, and food does not have an effect on a CT scan with contrast.
- Biguanide medication must be held for a test with contrast medium because it increases the risk of lactic acidosis, which leads to renal problems.
- Informed consent is not required for a CT scan. The admission consent covers routine diagnostic procedures.
- Pancreatic enzymes are administered when the pancreas cannot produce amylase and lipase, not when the beta cells cannot produce insulin.
The diabetic educator is teaching a class on diabetes type 1 and is discussing sick-day rules. Which interventions should the diabetes educator include in the discussion? Select all that apply.
- Take diabetic medication even if unable to eat the client’s normal diabetic diet.
- If unable to eat, drink liquids equal to the client’s normal caloric intake.
- It is not necessary to notify the health-care provider if ketones are in the urine.
- Test blood glucose levels and test urine ketones once a day and keep a record. 5. Call the health-care provider if glucose levels are higher than 180 mg/dL.
- The most important issue to teach clients is to take insulin even if they are unable to eat. Glucose levels are in- creased with illness and stress.
- The client should drink liquids such as regular cola or orange juice, or eat regular gelatin, which provide enough glucose to prevent hypoglycemia when receiving insulin.
- Ketones indicate a breakdown of fat and must be reported to the HCP because they can lead to metabolic acidosis.
- Blood glucose levels and ketones must be checked every three (3) to four (4) hours, not daily.
- The HCP should be notified if the blood glucose level is this high. Regular insulin may need to be prescribed to keep the blood glucose level within acceptable range.
The client received 10 units of Humulin R, a fast-acting insulin, at 0700. At 1030 the unlicensed assistive personnel (UAP) tells the nurse the client has a headache and is really acting “funny.” Which intervention should the nurse implement first?
- Instruct the UAP to obtain the blood glucose level.
- Have the client drink eight (8) ounces of orange juice.
- Go to the client’s room and assess the client for hypoglycemia.
- Prepare to administer one (1) ampule 50% dextrose intravenously.
- The blood glucose level should be ob- tained, but it is not the first intervention.
- If it is determined the client is having a hypoglycemic reaction, orange juice is appropriate.
- Regular insulin peaks in 2 to 4 hours. Therefore, the nurse should think about the possibility the client is having a hypoglycemic reaction and should assess the client. The nurse should not delegate nursing tasks to a UAP if the client is unstable.
- Dextrose 50% is only administered if the client is unconscious and the nurse sus- pects hypoglycemia.
The nurse at a freestanding health care clinic is caring for a 56-year-old male client who is homeless and is a type 2 diabetic controlled with insulin. Which action is an example of client advocacy?
- Ask the client if he has somewhere he can go and live.
- Arrange for someone to give him insulin at a local homeless shelter.
- Notify Adult Protective Services about the client’s situation.
- Ask the HCP to take the client off insulin because he is homeless.
- This is an example of interviewing the client; it is not an example of client advocacy.
- Client advocacy focuses support on the client’s autonomy. Even if the nurse disagrees with his living on the street, it is the client’s right. Arranging for someone to give him his insulin provides for his needs and allows his choices.
- Adult Protective Services is an organiza- tion investigating any actual or potential abuse in adults. This client is not being abused by anyone.
- The client needs the insulin to control the diabetes, and talking to the HCP about taking him off a needed medication is not an example of advocacy.
The nurse is developing a care plan for the client diagnosed with type 1 diabetes. The nurse identifies the problem “high risk for hyperglycemia related to noncompliance with the medication regimen.” Which statement is an appropriate short-term goal for the client?
- The client will have a blood glucose level between 90 and 140 mg/dL.
- The client will demonstrate appropriate insulin injection technique.
- The nurse will monitor the client’s blood glucose levels four (4) times a day.
- The client will maintain normal kidney function with 30-mL/hr urine output.
- The short-term goal must address the response part of the nursing diagnosis, which is “high risk for hyperglycemia,” and this blood glucose level is within acceptable ranges for a client who is noncompliant.
- This is an appropriate goal for a knowledge- deficit nursing diagnosis. Noncompliance is not always the result of knowledge deficit.
- The nurse is implementing an interven- tion, and the question asks for a goal which addresses the problem of “high risk for hyperglycemia.”
- The question asks for a short-term goal and this is an example of a long-term goal.
The client diagnosed with type 2 diabetes is admitted to the intensive care unit with hyperosmolar hyperglycemic nonketonic syndrome (HHNS) coma. Which assessment data should the nurse expect the client to exhibit?
- Kussmaul’s respirations.
- Diarrhea and epigastric pain.
- Dry mucous membranes.
- Ketone breath odor.
- Kussmaul’s respirations occur with diabetic ketoacidosis (DKA) as a result of the breakdown of fat, resulting in ketones.
- Diarrhea and epigastric pain are not associated with HHNS.
- Dry mucous membranes are a result of the hyperglycemia and occur with both HHNS and DKA.
- This occurs with DKA as a result of the breakdown of fat, resulting in ketones.
- The elderly client is admitted to the intensive care department diagnosed with severe HHNS. Which collaborative intervention should the nurse include in the plan of care?
- Infuse 0.9% normal saline intravenously.
- Administer intermediate-acting insulin.
- Perform blood glucometer checks daily.
- Monitor arterial blood gas results.
- The initial fluid replacement is 0.9% normal saline (an isotonic solution) intravenously, followed by 0.45% saline. The rate depends on the client’s fluid volume status and physical health, especially of the heart.
- Regular insulin, not intermediate, is the insulin of choice because of its quick onset and peak in two (2) to four (4) hours.
- Blood glucometer checks are done every one (1) hour or more often in clients with HHNS who are receiving regular insulin drips.
- Arterial blood gases are not affected in HHNS because there is no breakdown of fat resulting in ketones leading to meta- bolic acidosis.
Which electrolyte replacement should the nurse anticipate being ordered by the health-care provider in the client diagnosed with DKA who has just been admitted to the ICU?
- Glucose.
- Potassium.
- Calcium.
- Sodium.
- Glucose is elevated in DKA; therefore, the HCP would not be replacing glucose.
- The client in DKA loses potassium from increased urinary output, acidosis, catabolic state, and vomiting. Replacement is essential for preventing cardiac dysrhythmias secondary to hypokalemia.
- Calcium is not affected in the client with DKA.
- The prescribed IV for DKA—0.9% normal saline—has sodium, but it is not specifically ordered for sodium replacement. This is an isotonic solution.
The client diagnosed with HHNS was admitted yesterday with a blood glucose level of 780 mg/dL. The client’s blood glucose level is now 300 mg/dL. Which intervention should the nurse implement?
- Increase the regular insulin IV drip.
- Check the client’s urine for ketones.
- Provide the client with a therapeutic diabetic meal.
- Notify the HCP to obtain an order to decrease insulin.
- The regular intravenous insulin is contin- ued because ketosis is not present, as with DKA.
- The client diagnosed with type 2 diabetes does not excrete ketones in HHNS because there is enough insulin to prevent fat breakdown but not enough to lower blood glucose.
- The client may or may not feel like eating, but it is not the appropriate intervention when the blood glucose level is reduced to 300 mg/dL.
- When the glucose level is decreased to around 300 mg/dL, the regular insulin infusion therapy is decreased. Subcuta- neous insulin will be administered per sliding scale.
The client diagnosed with type 1 diabetes is found lying unconscious on the floor of the bathroom. Which intervention should the nurse implement first?
- Administer 50% dextrose IVP.
- Notify the health-care provider.
- Move the client to the ICU.
- Check the serum glucose level.
- The nurse should assume the client is hypoglycemic and administer IVP dextrose, which will rouse the client imme- diately. If the collapse is the result of hyperglycemia, this additional dextrose will not further injure the client.
- The health-care provider may or may not need to be notified, but this is not the first intervention.
- The client should be left in the client’s room, and 50% dextrose should be administered first.
- The serum glucose level requires a venipuncture, which will take too long. A blood glucometer reading may be ob- tained, but the nurse should first treat the client, not the machine. The glucometer only reads “low” after a certain point, and a serum level is needed to confirm exact glucose level.
Which assessment data indicate the client diagnosed with diabetic ketoacidosis is responding to the medical treatment?
- The client has tented skin turgor and dry mucous membranes.
- The client is alert and oriented to date, time, and place.
- The client’s ABG results are pH 7.29, PaCO2 44, HCO3 15.
- The client’s serum potassium level is 3.3 mEq/L.
- This indicates the client is dehydrated, which does not indicate the client is get- ting better.
- The client’s level of consciousness can be altered because of dehydration and acidosis. If the client’s sensorium is intact, the client is getting better and responding to the medical treatment.
- These ABGs indicate metabolic acidosis; therefore, the client is not responding to treatment.
- This potassium level is low and indicates hypokalemia, which shows the client is not responding to medical treatment.
The UAP on the medical floor tells the nurse the client diagnosed with DKA wants something else to eat for lunch. Which intervention should the nurse implement?
- Instruct the UAP to get the client additional food.
- Notify the dietitian about the client’s request.
- Request the HCP increase the client’s caloric intake.
- Tell the UAP the client cannot have anything else.
- The client is on a special diet and should not have any additional food.
- The client will not be compliant with the diet if he or she is still hungry. Therefore, the nurse should request the dietitian talk to the client to try to adjust the meals so the client will adhere to the diet.
- The nurse does not need to notify the HCP for an increase in caloric intake. The appropriate referral is to the dietitian.
- The client is on a special diet. The nurse needs to help the client maintain compli- ance with the medical treatment and should refer the client to the dietitian.
The emergency department nurse is caring for a client diagnosed with HHNS who has a blood glucose of 680 mg/dL. Which question should the nurse ask the client to determine the cause of this acute complication?
- “When is the last time you took your insulin?”
- “When did you have your last meal?”
- “Have you had some type of infection lately?”
- “How long have you had diabetes?”
- A client with type 2 diabetes usually is prescribed oral hypoglycemic medications, not insulin.
- The client could not eat enough food to cause a 680-mg/dL blood glucose level; therefore, this question does not need to be asked.
- The most common precipitating factor is infection. The manifestations may be slow to appear, with onset ranging from 24 hours to 2 weeks.
- This does not help determine the cause of this client’s HHNS.
The nurse is discussing ways to prevent diabetic ketoacidosis with the client diagnosed with type 1 diabetes. Which instruction is most important to discuss with the client?
- Refer the client to the American Diabetes Association.
- Do not take any over-the-counter medications.
- Take the prescribed insulin even when unable to eat because of illness.
- Explain the need to get the annual flu and pneumonia vaccines.
- The American Diabetes Association is an excellent referral, but the nurse should discuss specific ways to prevent DKA.
- The client should be careful with OTC medications, but this intervention does not help prevent the development of DKA.
- Illness increases blood glucose levels; therefore, the client must take insulin and consume high-carbohydrate foods such as regular Jell-O, regular popsicles, and orange juice.
- Vaccines are important to help prevent ill- ness, but regardless of whether the client gets these vaccines, the client can still de- velop diabetic ketoacidosis.
The charge nurse is making client assignments in the intensive care unit. Which client should be assigned to the most experienced nurse?
- The client with type 2 diabetes who has a blood glucose level of 348 mg/dL.
- The client diagnosed with type 1 diabetes who is experiencing hypoglycemia.
- The client with DKA who has multifocal premature ventricular contractions.
- The client with HHNS who has a plasma osmolarity of 290 mOsm/L.
- This blood glucose level is elevated, but not life threatening, in the client diagnosed with type 2 diabetes. Therefore, a less ex- perienced nurse could care for this client.
- Hypoglycemia is an acute complication of type 1 diabetes, but it can be managed by frequent monitoring, so a less experienced nurse could care for this client.
- Multifocal PVCs, which are secondary to hypokalemia and can occur in clients with DKA, are a potentially life-threatening emergency. This client needs an experienced nurse.
- A plasma osmolarity of 280 to 300 mOsm/L is within normal limits; therefore, a less experienced nurse could care for this client.
Which arterial blood gas results should the nurse expect in the client diagnosed with diabetic ketoacidosis?
- pH 7.34, PaO2 99, PaCO2 48, HCO3 24.
- pH 7.38, PaO2 95, PaCO2 40, HCO3 22.
- pH 7.46, PaO2 85, PaCO2 30, HCO3 26.
- pH 7.30, PaO2 90, PaCO2 30, HCO3 18.
- This ABG indicates respiratory acidosis, which is not expected.
- This ABG is normal, which is not expected.
- This ABG indicates respiratory alkalosis, which is not expected.
- This ABG indicates metabolic acidosis, which is expected in a client diagnosed with diabetic ketoacidosis.
The client is admitted to the ICU diagnosed with DKA. Which interventions should the nurse implement? Select all that apply.
- Maintain adequate ventilation.
- Assess fluid volume status.
- Administer intravenous potassium.
- Check for urinary ketones.
- Monitor intake and output.
- The nurse should always address the airway when a client is seriously ill.
- The client must be assessed for fluid volume deficit and then for fluid volume excess after fluid replacement is started.
- The electrolyte imbalance of primary concern is depletion of potassium.
- Ketones are excreted in the urine; levels are documented from negative to large amount. Ketones should be mon- itored frequently.
- The nurse must ensure the client’s fluid intake and output are equal.
